We all know Cubix and Cyclone, but has anyone tried cheaper alternatives? For example:

I have a netstor na250a-gpu, i used 24/7 since a year, it run perfectly. I have installed 2xgtx480, 1xred rocket, 1xusb3, 1xsonnet e4p, all running with a hackintosh.
Mine is 8x lanes, and ir run very very fast

Sonnet, Magma, Maxx are all putting out thunderbolt PCI-e expansion cases very soon, the first two for less than $1,000.

Well... Never used it so can't comment on how well it actually works. However, it uses a PCIe 2.0 X4 interface. So with that, you are getting 1/4 of the bandwidth that you get with the Cubix desktop units at 1/3 the price. So if you want to look at it in terms of MB/s for your money, it's not that great of a bargain. :)

I think the number of lanes depend a lot of type of working. In my case with davinci i have 8, but with 16 imo it will not be faster. I tested some different configs and always same speed. For a 1xgpu x4 can be good enought, but for 4 gpu maybe not. For redrocket i must test, but in fact it is pciex8 v1, that is the same bandwith than pciex4 v2.
